Radioisotopes have energy densities up tole9 Jg, whereas chemical-bonds typically store energies less than 1e4 Jg. Energy density is only a necessary condition for usefulness as an energetic material. Detailed here is the final report of a search for novel mechanisms for the rapid and controllable release of nuclear energy within radioisotopes. In particular, the focus of this work was to theoretically, numerically, and experimentally quantify the cross-sections or nuclear reactions induced by heavyions or energetic neutrons. Radioisotopes were studied which are energy-rich le9 Jg and are more abundant or naturally occurring with half-lives up to billions of years. The nuclear reaction cross sections were quantified by changes in the normal radioactive decay rate bum-up or measuring the presence of a disturbed secular equilibrium enhanced secondary decay.
